What to do if Centech Battery Charger ammeter needle moves up to full charge, then drops to zero?
- KKristy HarperJul 31, 2025
If the ammeter needle on your Centech Battery Charger moves to full charge and then drops to zero while making a clicking noise, several issues could be at play. First, double-check the connection polarity; if it's wrong, turn off the charger and correct the cable lead connections. The battery might be completely dead, in which case you should continue charging it, allowing the charger to reset itself until the battery reaches a chargeable level. It could also indicate a defective battery, so consider checking or replacing it. The charger engine starter may be resetting itself after a circuit overload; in that case, wait for the charger to automatically reset. Finally, the circuit breaker might be cycling, potentially due to the wrong switch position.
